All three descriptors for #3 (sexual thing, fetish, role play) describe me, so that’s what I am. In the course of this, I’ve developed a true liking, even love of women’s clothes, so I’m a #1 too.
My crossdressing is at core a function of a dominant and submissive relationship. I crossdressed as a child in my mother’s and sister’s clothes and my early story is a standard one shared by many. I later told my wife after many years of hiding it, and for years I was someone who dressed when home alone and whose wife was only lukewarm about it (mostly for safety reasons). It was only after we started exploring a D/s relationship that it became what it is now. I don’t have any feelings of dysphoria or gender fluidity, but rather I thrive off of the feelings of being a man who is made to be submissive to his overachieving wife, to the point of being a stay at home housewife and wearing dresses every day. It’s the friction of being a man and made to do this that drives me. If I woke up as a woman tomorrow, that feeling would disappear and I would probably just wear jeans and a tshirt. My wife would also lose interest because she wants to dominate a man (which gives her a rush) not a woman.
So I guess I’m a bit of a different kind of crossdresser altogether. I don’t see too many stories like mine on CDH (a few, yes), but that’s ok. I learn from everyone and enjoy the diversity of this community.
